4. ceratotherium:. 



Head elongate, produced behind ; forehead flat ; nose very broad, 

 square at the end; upper lip bovine, rounded. Horns two, very 

 unequal, hinder small. Skin smooth, not divided into shields. 

 Shoulder with a weU-marked hunch. SkuH elongate ; the portion 

 of the skull behind the hinder edge of the last or seventh grinder as 

 long as the one in front of it ; occiput erect, the upper margin 

 much produced behind the condyle ; forehead concave ; nose straight, 

 rounded ; nasal bones very broad, convex above, truncated, with a 

 sharp edge in front ; lower jaw thick, tapering in front; molars large ; 

 teeth-line straight. 



The skuH of the very young animal has a very convex, nearly 

 hemispherical prominence on the nasals, and is broad and rounded 

 in front ; but the prolongation of the hinder part of the skuU is 

 shown in the fcetal skull in which the milk-grinders are only just 

 appearing, the proportion of the binder and anterior portions being 

 nearly the same as in the adult skulls ; the occiput is erect, without 

 any marked projecting crest.
